“…Porous organic polymers (POPs) have emerged as potential adsorbents for many pollutants including CO 2 , heavy metals, organic vapors, dyes, etc 17 – 22 . Constructed from light atoms (H, C, N, O), POPs often show excellent thermal and chemical stabilities, high porosity, and tuneable chemical functionality, and thus can be easily tailored toward targeted applications 23 .…”

The capture and safe storage of radioactive iodine (129I or 131I) are of a compelling significance in the generation of nuclear energy and waste storage. Because of their physiochemical properties, Porous Organic Polymers (POPs) are considered to be one of the most sought classes of materials for iodine capture and storage. Herein, we report on the preparation and characterization of two triazine-based, nitrogen-rich, porous organic polymers, NRPOP-1 (SABET = 519 m2 g−1) and NRPOP-2 (SABET = 456 m2 g−1), by reacting 1,3,5-triazine-2,4,6-triamine or 1,4-bis-(2,4-diamino-1,3,5-triazine)-benzene with thieno[2,3-b]thiophene-2,5-dicarboxaldehyde, respectively, and their use in the capture of volatile iodine. NRPOP-1 and NRPOP-2 showed a high adsorption capacity of iodine vapor with an uptake of up to 317 wt % at 80 °C and 1 bar and adequate recyclability. The NRPOPs were also capable of removing up to 87% of iodine from 300 mg L−1 iodine-cyclohexane solution. Furthermore, the iodine-loaded polymers, I2@NRPOP-1 and I2@NRPOP-2, displayed good antibacterial activity against Micrococcus luteus (ML), Escherichia coli (EC), and Pseudomonas aeruginosa (PSA). The synergic functionality of these novel polymers makes them promising materials to the environment and public health.

“…For the PPBPI-CRs, there were obvious capillary hysteresis loops at the medium and high pressure regions (P/P 0 = 0.1−0.9), indicative of the presence of mesopores in the pore channels and the swelling effect of adsorbate gas molecules and PPBPI-CR skeletons. 33 The micropore volumes and the micropore ratios (V micro /V total ) of PPBPI-CRs compared to PPBPIs were higher, which indicated that more micropores were produced…”

Three cross-linked porphyrin-based polyimides (PPBPI-H-CR, PPBPI-Mn-CR, and PPBPI-Fe-CR) were synthesized from 5,10,15,20-tetra(4-aminophenyl)porphyrin (TAPP) and 2,5-bis(3,4-dicarboxyphenoxy)-4′-phenylethynyl-biphenyl dianhydride (PEPHQDA) via polymerization and thermal cross-linking reactions. Their chemical structures were confirmed by FTIR and 13C CP/MAS NMR. SEM, XRD, and TEM analyses were used to observe their surface and nature characteristic morphologies as well as pore channels. DSC and TGA were carried out to confirm their cross-linking behaviors and thermal stabilities. PPBPI-H-CR showed the largest specific surface area (733 m2 g–1) and the highest CO2 uptake (2.26 mmol g–1 at 273 K and 1 bar) among the PPBPI-CRs. PPBPI-Mn-CR and PPBPI-Fe-CR compared to PPBPI-H-CR exhibited smaller specific surface areas, more uniform pore sizes around 1.2 nm, and larger isosteric heats of adsorption due to the presence of coordination sites for manganese and iron. PPBPI-CRs exhibited separation factors of CO2/N2 (31.48, 35.09, and 45.34) and CO2/CH4 (13.17, 9.06, and 12.99).

A hierarchically porous monolith comprising the melamine-based microporous organic polymer (MOP) particles was prepared by the Pickering emulsion templating method. The MOP particles were synthesized by polycondensation of melamine and terephthaldicarboxaldehyde. Because of the balanced presence of hydrophilic nitrogen containing groups and hydrophobic benzene rings, the MOP particles showed good amphiphilicity. A Pickering emulsion was prepared, where cyclohexane droplets with an average size of about 25 μm were stabilized by the MOP particles (3.4 wt %) in an aqueous continuous phase. The cyclohexane internal phase fraction was slightly higher than 60%. The emulsion showed no phase separation even after two weeks. The Pickering emulsion containing a small amount of polyvinyl alcohol (1 wt %) in a continuous phase as a reinforcement was used as a template for the fabrication of a monolith of the MOP particles. The Pickering emulsion was freeze-dried to produce a hierarchically porous monolith. The MOP monolith possessed macropores templated by the oil droplets and micro- and mesopores in the MOP particles that constituted the macropore walls. The MOP monolith exhibited a high dye absorption ability in a solution of RhB in chloroform and a good absorption capacity for nonpolar organic solvents. After the absorption, the monolith could be regenerated by solvent exchange with cyclohexane and subsequent freeze-drying.
